Abstract (en)
[origin: EP3085745A1] The present invention relates to a colored fine particle dispersion including emulsified particles including a pigment and a polymer containing a constitutional unit derived from a compound (A) represented by the following general formula (I) and a constitutional unit derived from a polymerizable monomer component including a hydrophobic vinyl-based monomer: wherein BO is a butyleneoxy group; EO is an ethyleneoxy group; M is a cation; m represents an average molar number of addition of BO and is a number of not less than 1 and not more than 10; and n represents an average molar number of addition of EO and is a number of not less than 4 and not more than 25; a process for producing the colored fine particle dispersion; a water-based ink for ink-jet printing including the colored fine particle dispersion; and a use of the colored fine particle dispersion as a colorant for a water-based ink for ink-jet printing. The water-based ink for ink-jet printing using the colored fine particle dispersion is excellent in storage stability as well as rub fastness when printed on a low-water absorbing recording medium, and can be prevented from suffering from increase in viscosity thereof when concentrated.
